Dichotomous Keys Identify Organisms
Dichotomous keys versus evolutionary classification
Dichotomous keys contain pairs of contrastingdescriptions.
After each description, the key directs the user toanother pair of descriptions or identifies the organism.
Example:1.a) Is the leaf simple? Go to 2b) Is the leaf compound? Go to 3
2.a) Are margins of the leaf jagged? Go to 4b) Are margins of the leaf smooth? Go to 5
